Abstract

In healthy individuals, cortisol levels exhibit a circadian pattern, peaking in the morning and decreasing the rest of the day. Studies are inconclusive as to the relationship between high total cortisol levels and obesity, prediabetes, and type 2 diabetes. Since cortisol levels are circadian, many naturopathic physicians use a salivary test performed at four time points during the day to measure the overall pattern of secretion, rather than relying upon a blood draw from a single time point. Some physicians hypothesize that a dysregulated pattern of cortisol is more indicative of diabetes risk than a high mean cortisol level. A retrospective chart review was performed on obese, prediabetic, and type 2 diabetes patients in order to test this theory. The goals of this study were to determine whether people with, or at risk for, type 2 diabetes have abnormal circadian cortisol patterns and dehydroepiandrosterone (DHEA) levels. The chart review demonstrated four patterns of cortisol secretion, one of which is circadian, in this population.
